OASING-SWAGE,

Specification of Letters Patent.

Patented Dec. 2?, 191%.

Application filed December 18, 1909. Serial 2:10. 533,897.

To all whom it may concern:

Be it known that I, RYLAND W. Ensues, a citizen of the United States,residing at Vale, in the county of Malheur and State of Oregon, haveinvented new and useful Imrovements in Casing-Swages, of which thefollowing is a specification. The invention relates to an improvedcaslng swage, being more particularly directed to an implement adaptedto be adjusted within the casing tube or pipe section and operated tocorrect any surface indentation or irregularity in said section.

The main object of present invention is the provision of a sii 'ageembodying separable sections and including with said sections amechanism whereby the sections may be separated at the will ofthehoperator to bear with practically any desired force upon theinteriorsurface of the casing of the section, the formation of the swagesections being such that in size they will force the material of thecasing against which they bear;

into the normal plane of the casing thereby obliterating anyindentations or other irregularities in the' casing wall and in effectreforming said casing to provide a true cylindrical interior form. I j

The invention in its preferred detailsggf construction will be describedin the following specification, reference being had particularly to theaccompanying drawings, in' which: Figure 1 is n side elevation of the improved swage. Fig. 2 is an end view of the same. Fig. 3 is a brokenvertical section, artly in elevation. Fig. 4 is a reduced viewillustrating the use of theswage.

Referring particularly to the accompanying drawings, the improved swageis made up of two members 1 and 2, the former of which will behereinafter termed the base member and the latter the anvil member. Thebase. member is of approximately cylindrical form and of a thickness inaccordance with the material to be operated upon. The exterior surfaceof the base is, for the greater portion ofits length, disposed at rightangles to' its plane of movement,providing a bearing surface 3, whilethe ends beyond said bearing surfaces incline inwardly, as at 4, wherebyto provide for theeasy introduction of the implement into the casing.The anvil member 2 is preferably of greater thickness than the basemember and of less circumferential extent, the rurvatiuc of the outer orbearing surface of said anvil mem' ber being preferably on a smallerradius than the curvature of the base member. Theexterior surface of theanvil 1neinber;,cor1esponds to the similar surface of the base member,being formed to provide a central bearing surface 5 arrangedoppos'itethe hearing surface of the base member and inwardly inclinedend 6. The anvil member is-centrally provided with aradially arrangedtubular projection-7 i nteriorly threaded at 8, while the baseniember isformed with a similar radia lg/proj rior bore l0/ The projections 7 and9 are braced from the respective members by the usualwebs 11, so that astrong and substantial structure is provided.

B'otatably tll'itlllg fl in the bore 10 of the base member projection isan operating rod 192 terminally threaded at 13- to coliperate with thethreadsS in the bore of the projection 7 A worm gear 14 is secured uponthe "rod 12 in any preferred manner,

as for example by means of a Set screw 15. The gear is thus disposedbetween the proximate of the projections 7 and 9 so that when the partsare in collapsed or inoperative positions the inner ends of theprojections Will bear against opposing surfaces of the gear. Mounted inspaced cars 16 projecting from the base member adjacent one edge of thecylindrical portion thereof is a shaft 17 on which intermediate the earsis formed a worm screw 18. The parts are so arranged and ofsuch relativesizes that the thread on the worm screw will engage the teeth on thegear 14 and rotate the latter in the revolution of the shaft 17. Theshaft 17, which may be of any desired length, is terminally ection 9having an inteends provided with an operating handle or crank 19.

In use, assuming that the swage is to be put in service to obliterate anindentation, as 20, in a casing tube, as 21, the parts are withdrawn tooperative position that is the shaft 17 is operated so that through themedium of the threaded connection of the rod-12 and The operation iscontinued until the pressure t ial. extent is sutiieient to cause theanvil member to force outwardly the material forming the indentatien,thereby dbiiterating the same and restoring the normal form of the c:sing.

It is obvious, of course, that any irregw larity in the interior surfaceof the casing, other than a fracture, can quiekiy obliterated by theproper appiication 0f the swage. The impien'ient i s te be made in any rlesired size and the plane oi. the curvature of the respective base andanvii members 'Wiii be varied to suit different requirements.

Having thus described the invention, What is claimed as new, is

l. A swag'e including auanvii member, a base member hz-rvinga greatercircumferenthan the anvil member, anoperating rod having threadedengagement with one of said members, a gear secured upon the red andmeans for v An interior swaging implement com? prising a base member, ananvil member, an operating rod having threaded connection with one ofsaid members, a gear mounted upon the rod, a worm screw base member andcooperating with the gear, and a shaft coiiperating with the worm screw.

In testimony whereof-I aiiix in presence of two witnesses.
